Database tools The usability and functionality of the database tools is improved. There is a new UI for setting up database authentication. JDataStore JDataStore is faster and more flexible. The underlying connection pool provides significant performance gains. JBuilder 4 s support for JTA allows JDataStore connections to participate in distributed transactions using standard XA interfaces. JDataStore Explorer allows you to create and manipulate tables graphically. It can create indexes for its tables. JDataStore now supports cross joins, inner joins, and left, right, and full outer joins. (In this release, specify join columns by using the natural or using keywords.) JDataStore supports the SQL-92 join sequence and the JDBC oj escape sequence. It supports scalar subqueries. JDataStore Server options are under the Options tab. The new UI shows more information about the server, including: Users connected. Open databases. History of events. Database authentication allows you to password protect your JDataStore. There are two stages to the process: password protecting it, and opening it for different levels of access. For more information on JDataStore, see the JDataStore Developer s Guide.

Application server support Part IV, Enterprise JavaBeans Developer s Guide of the Enterprise Application Developer s Guide provides a comprehensive overview of what these features do and how to use them. Application server support JBuilder 4 allows you to choose which application server to run on, allowing you to maintain different configurations for each one. To do so, select Project|Project Properties, select the Run tab and then the EJB tab. Default parameters are for the Inprise Application Server, but BEA s WebLogic Server 5.1 can also be used directly from the JBuilder IDE: choose Tools|Enterprise Setup, select the Application Server tab, select the WebLogic tab, then set the directory path. You may plug in other application servers through the OpenTools API. JDBC connections are verified by JBuilder 4. Column data is available on the Persistence tab of the Deployment Descriptor Editor (DDE) view in the content pane. The Deployment Descriptor Editor is compliant with JDK 1.3 and can read and write to EJB groups. The Deployment Descriptor Editor is integrated into the JBuilder interface. When used with WebLogic , it creates WebLogic deployment descriptors, so you can target your beans for the WebLogic server from within JBuilder. Team development JBuilder 4 provides features that make team development faster, smoother, and easier. Project files (.jpr and .jpx) are in two parts: private and shared. Windows, watches, and breakpoints are stored in the private side, while libraries and compiler options are stored in the shared side. This simplifies the process of sharing projects. Version tracking and control JBuilder 4 provides revision support in every edition. To see version information for a file, click on the History tab at the bottom of the content pane. Tabs on the History page provide different views of revision information. Availability of views depends on your JBuilder edition. For more information on the History page, put your cursor in the History page and press F1. JBuilder automatically keeps backup copies of your file. You can store backup files outside your source directory, so it s easier to share your 2-4 Learning Java with JBuilder

Enterprise JavaBeans For more information, see Using InternetBeans Express in Part III, Distributed Application Developer s Guide of the Enterprise Application Developer s Guide. Enterprise JavaBeans JBuilder 4 makes it easier to create and deploy both session and entity bean components. A number of wizards (including EJB Group) streamline the creation, handling, and deployment of Enterprise JavaBeans. JBuilder 4 provides tools that simplify modeling and server configuration. It has Inprise Application Server s Deployment Descriptor Editor built into the JBuilder IDE. JBuilder supports BEA s WebLogic Server 5.1. One new aspect of JBuilder 4 is the EJB Group functionality. Each EJB Group represents a single deployable JAR that is created automatically by Make or Rebuild. Using the EJB Group wizard, you can also migrate existing EJBs. You can have multiple EJB groups per project. The Entity Bean Modeler lets you create entity beans that map to existing tables. The modeler will both create all the necessary Java code and update the deployment descriptor stored in the EJB Group. Select an EJB Group to bring up the Entity Bean Modeler dialog. With JBuilder 4, you can: Create entity and session beans using EJB wizards. Map entity beans to existing tables with the Entity Bean Modeler. Create EJB groups with the EJB Group wizard, so you can have any number of EJBs in a given application. Migrate existing EJBs into a new group or create an empty group from the EJB Group wizard. Use multiple EJB groups in a project. Create deployable JARs automatically using Make or Rebuild. View JAR contents in the node viewer. Test your applications in a local container or on your EJB 1.1-compliant application server with the Test Client wizard. Run EJBs from the EJB Run dialog in a local container or application server selected for the project. Deploy EJBs automatically when you run or debug them. View and edit your application server deployment descriptor using the Deployment Descriptor Editor. To select any of the wizards or modelers mentioned above, choose File| New, select the Enterprise tab, and choose from the icons available. What s new in JBuilder 4 2-3
